说明：   51单片机的_中文拼音输入法_c源程序 拼音输入法杳询函数: unsigned char code * py_ime(unsigned char input_py_val[]) input_py_val为已输入的拼音码字符串头指针， 反回值为中文的起始地址，当为0时，杳询失败 应用举例： { unsigned char input_string[]={"bang"} unsigned char chines_string[100] sprintf(chines_string,"％s",py_ime(input_string)) }(51 Singlechip _ Chinese Pinyin input method _c source disappeared consultation Pinyin input method function: unsigned char code* py_ime (unsigned char input_py_val []) input_py_val for Pinyin input first code string pointer, and anti-back value of Chinese starting address, as 0:00, dark and quiet consultation, for example the failure of the application: (unsigned char input_string []={ bang ) unsigned char chines_string [100] sprintf (chines_string, s , py_ime (input_string))))

说明：  这是一个简单的数据采集卡的例子程序，主要介绍编写数据采集卡的驱动的基本流程。MakeFile文件的编写等等。。。 希望对新手有帮助(This is a simple example of data acquisition card procedures, mainly the preparation of data acquisition card driven by the basic process. MakeFile documentation and so on. . . I hope to help novice)

带主动两轮主动差速的双电机PID调速模块，实现对电机的调速，尤其可以适用于对后轮双独立电机驱动方式的主动差速调节。(The dual motor PID speed regulation module with active two wheel active differential can realize the speed regulation of the motor, and can be applied to the active differential regulation of the driving mode of the dual motor of the rear wheel.)

USB与51单片机的连接使用，采用PDIUSB12接口芯片(51 single-chip USB connectivity and use, the use of PDIUSB12 interface chip)

本实验将实现如下功能：本章我们在UCOSII里面创建3个任务：开始任务、LED0任务和LED1任务，开始任务用于创建其他（LED0和LED1）任务，之后挂起；LED0任务用于控制DS0的亮灭，DS0每秒钟亮80ms；LED1任务用于控制DS1的亮灭，DS1亮300ms，灭300ms，依次循环。(This experiment will achieve the following functions: in UCOSII, we create three tasks: start task, LED 0 task and LED 1 task, start task for creating other tasks (LED 0 and LED 1), then hang up; LED 0 task for controlling the brightness of DS0, DS0 80 ms per second; LED 1 task for controlling the brightness of DS1, DS1 300 ms. 300 ms, cycle in turn.)

用mage128产生spwm驱动ir21094构成的逆变电源，小功率时波形正常。(Switching power supply system procedures mage128 parallel development board to achieve two-way current pro rata, the regulator output.)

SD2.0和3.0中文协议，希望能帮到大家学习sd卡(sd2.0 sd3.0 spec hope to help you)

EMDA控制器可以在没有cpu的参与下完成映射存储空间的数据传输，这些数据的传输可以是片内外设，片内存储器之间。(EMDA controller can be done without the participation of CPU mapping storage space of data transmission, the data transmission can be set inside and outside, between internal storage.)

说明：  通过读出SD卡中320x240像素、16位BMP图片的HEX数据，依次写到屏上，还原图片(Read SD card in 320x240 pixels, 16 BMP picture HEX data, in turn written to the screen to restore the picture)

通过STM32单片机采集ADC的数值，然后通过串口传送给上位机进行接收()
